85/110 Amp batteries

[colin(bridgend)]

I have recently purchased a new 110amp battery. However my neighbour. a fellow caravanner, reckons that as we always use E.H.U. on site I have wasted my money and needed only to buy a 85amp battery. The caravan is at present on my drive and connected to the mains. Apart from the amperage what are the advantages of the larger battery.

hi,

hes probably right in his comment,unless you use the van on non electric pitches/sites a small ampage battery would suffice.if you have a motor mover fitted...then 110 amp battery would be appropriate

I have a Powrwheel motor mover on my Swift Challenger 530 and have had a 85amph battery for the last five years, with no problems at all. I leave the van in storage for months over the winter and there is still plenty of power to move the van out of its bay to hook up. Why carry all that extra weight when it is not really required.

My current Avon 110 anps is 6+ years old now.

With the heavy TA I personally think it is worth the extra few quid and few kgs particularly with the motor mover.

There are many places where EHU is not available so the larger amperage steps into its own.

If you don't have a mover and always use an EHU then by all means go for 85amps.

I have a 110 because I very rarely have EHU just the solar panel and a heavy twin axle that I need to use the motor mover to get on and off a gravel driveway. If I didn't have these two considerations I would probably just have the 85

Hello Colin, and Klarky,

If you actually work out how much power in Ahr's the majority of m0otor movers uses to position a caravan on site or at home you may be surprised to find that in it only amounts to about 2Ah!

The only possible reason for looking for a 110Ah battery over an 85Ah would be if you persistently use non electrified sites, or the maximum instantaneous current load of the battery is not big enough for the stall current of the mover, and that depends on the make and age of battery.

I bought a new 85ah battery 4 years ago, then fitted a mover 1 year later, it`s been fine but I use EHU on sites
